Abstract - This paper evaluates the properties of incinerator bottom ash from WTE (waste to energy) Plant, Essel MSW Pvt Ltd, Jabalpur to see what uses the material could be put to after incineration. The properties of the material make it suitable for use as fills, low-cost road sub-grades, sub-bases, and cement concrete. The M20 concrete mix was designed and produced by replacing cement with Municipal solid waste incinerator ash partially. Cement was replaced with 0%, 5%, 10%, 15%, 20%, 25% and 30% with municipal solid waste incinerator ash by weight. The compressive strength test was carried out to evaluate the properties of the M20 grade of concrete mix. The 7 days and 28 days compressive strength were increased by 28.05% and 15.31% in M20 concrete respectively at 10% cement replacement with municipal solid waste incinerator bottom ash (MSWIA).

1. INTRODUCTION
The incineration of municipal solid waste has significant benefits as it can reduce the volume and the mass of the waste by about 90% and 70%, respectively. Municipal solid waste is collected and burned in an incinerator; the by-products of the combustion process are collected. Bottom ash typically accounts for 80% of the whole amount of by-products in the MSWI plants. Municipal solid waste incinerator (MSWI) bottom ash is the ash that is left over after waste is burnt in an incinerator. This ash contains glass, brick, rubble, sand, grit, metal, stone, concrete, ceramics and fused clinker as well as combustive products such as ash and slag. Cement and aggregate, which are the most important constituents used in concrete production, are the vital materials needed for the construction industry. This necessity led to a continuous and increasing demand for natural materials. Parallel to the need for the utilisation of the natural resources emerges a growing concern for protecting the environment and need to preserve natural resources, by using alternative materials that are either recycled or discarded as a waste. One of the possibilities is to use Municipal Solid Waste Incineration (MSWI) ashes in concrete production. Studies have been carried out to investigate the possibility of utilizing for broad range of material as a partial replacement material for cement & aggregate n the production of concrete. Concrete has been a major construction material for centuries. Moreover, it would even be of high application with the increase in industrialisation and urbanisation. Concrete construction so far is mainly based on the use of natural resources. The conservation of natural resources is the need of the hour, and it is essential to have a look at the different alternatives. Among them lies the recycling mechanism. This process gives a two-fold advantage. One is that it can prevent the depletion of the scarce natural resources and the other is the prevention of different used(waste) materials from their severe threats to the environment.
